Used in pharmaceutical research as an intermediate in the synthesis of bioactive compounds, particularly in developing central nervous system agents. Its protected piperazine structure allows selective modification, making it valuable in creating serotonin or dopamine receptor modulators. Commonly employed in medicinal chemistry for structure-activity relationship studies due to the electron-withdrawing dichlorophenyl group influencing binding affinity. Also utilized in the preparation of analogs for drug discovery programs targeting neurological disorders.
